JediMark (Mark Watkins) is the author of SleepyHead. He is an Australian software developer with a love of all things Open Source.
He has moderate Sleep Apnea, and uses a Philips Respironics RemStar Auto (System One) machine.
Among other crud, he also suffers from chronic fatigue, frequent headaches and a looming "brain fog", which spoils his coding fun quite often.
